Yeah, psycopg2 is definitely installed...

Hmmm...well that isn't working either - same error.  My method for verifying it's picking up the right settings.py is by putting a syntax error in the settings.py it should be using and seeing that it generates an error.  This is the settings.py file in the directory below my app directory and that includes url.py and wsgi.py...

Ok. I would try setting the ENGINE value to sqlite3 and try running syncdb again. If that works (which it should), then we can presume it's a configuration access problem with the DB.

NO, just me messing around that it made no difference.  I have the db access to all and trust and the error doesn't change no matter what I use there.  It feels like it could be a permissions problem, but I don't know how to track it down other than to verify I can access postgres via psql which I can do...

First off, I am a newbie to django, python and postgres - so I suspect I am missing something obvious, but I am stumped.  Any ideas will be gratefully accepted...

I get the popular "Improperly configured settings.DATABASES" error message when I run syncdb on my test app.  I am running:

django 1.4.3

postgres 9.2

MAC OS 10.6.8

I have verified that it is picking up the right settings.py file (the one in the app subdirectory) so I assume there is either something wrong with the settings I have entered or something wrong with postgres.  How does one debug this??

I can connect to my database via psql, but nothing I have tried seems to work and there seems to be very little I can do to actually debug what the problem is...when the syncdb doesn't work, how do you debug to figure out what exactly isn't working???

I would expect a different error, but are you certain that psycopg2 is installed?

I noticed that you are using djcelery (which I know nothing about), but have you tried getting everything working without it first? There's a line in your settings that says

DATABASES['default'] = dj_database_url.config()

Could this be trashing the database setting somehow?
